Notes
1. fp = 55.25 MHz; Vp = 46 dBmV;
fq = 343.25 MHz; Vq = 46 dBmV;
measured at fp + fq = 398.5 MHz.
2. Measured according to DIN45004B:
fp = 440.25 MHz; Vp = Vo = 63 dBmV;
fq = 447.25 MHz; Vq = Vo −6 dB;
fr = 449.25 MHz; Vr = Vo −6 dB;
measured at fp + fq - fr = 438.25 MHz.
3. The module normally operates at VB = 24 V, but is able to withstand supply transients up to 30 V.
